SOURCE: ti 84 plus problem

The calculator only displays from -10 to 10 on the x and y axes, and both of your lines are outside of that range. However, it is easy to change that.

1. Hit the gray "WINDOW" button that is directly under the screen
2. Change "Xmax" to 150
3. Change "Ymax" to 200

Remember to change both of those values back to 10 when you are done with this problem!

Here's how to graph it:
1. Hit the "Y=" button
2. Enter your first equation after Y1, and your second equation after Y2
3. Look over both the equations to make sure you typed them correctly
4. Hit the "GRAPH" button
5. If you don't see the intersection you will need to adjust Xmax and Ymax again
6. Hit Hit "2ND" and the "TRACE" to bring up the "CALC" menu
7. Scroll down to "intersect" and hit enter
8. Hit enter 3 times (You use the first and second curve options when you have more than 2 lines)
9. It should display the coordinates at the bottom
10. I got (76, 142.1) for the intersection

Thanks for asking this question! I used to do this a much harder way, but while I was calculating the answer to your question I hit a wrong button and accidentally found this method!

2c + 6 + 7c = 8


To solve this with a ti-84 press [math] and select solve from the menu. This will open the equation solver. Type in your equation
(Note: you may need to put it in the form with 0=, So the equation would be 0 = 2c + 6 +7c - 8 ). Then press
enter or arrow down button.

How to simplify the equations in ti 84 ??


You cannot do it with this calculator. It does not have a Computer Algebra System (CAS). Try a TI89 Titanium, a TI 92PLUS, a TI 200PLT or a TI-Nspire CAS.
However, they may exist other programs on education.ti.com or ticalc.org. Search these sites and you may be lucky.

Getting more than 10 equations into y=


The TI 83, 84 seris can not store more than 10 equations. the TI 86 and above can have infinate, but not the 83, 84s. If you have catalog help in your apps, you can run that, and it will be able to tell you all the syntax of every function it has.
